I would like to ask for help; I need only appear the cpanel login botton to certain services, I mean if the customer have various services, only shown the cpanel botton for those services that is could.

I have this:

<code>

{if $moduleclientarea}

{if $pid eq "34" and $pid eq "35" and $pid eq "29"}hello{/if}{else}

{$moduleclientarea|replace:'modulebutton':'btn btn-info btn-sm'}

{/if}

</code>

But is not working (Note: service 34, 35 and 29, those are I do not want to show login botton)

Never mind is fixit:

{if $moduleclientarea and $pid neq "34" and $pid neq "35" and $pid neq "29"}

{$moduleclientarea|replace:'modulebutton':'btn btn-info btn-sm'}

{else}

{/if}
